what is that splines

[400exrider0004]

the splines I think are the little teeth that connect to the rod that goes into the motor. THe little splines on the sprocket wear out and can cause the sprocket to come off! I changed my sprocket from a 15 tooth to a 14 tooth today, and the splines were in perfect condition. So you dont need to replace the sprocket that often.
